First of all you need to see why relaying is being allowed.
It is sometimes necessary to accept smtp from localhost because some
muas put messages in like this.
to do relay testing try this:

exim -bh ip.address.not.hostname
helo fully.qualified.domain.name
mail from:email.address at valid.domain
rcpt to:valid.target at domain.name
data
tra la la la
.
Note that the above was a fullstop on a line by itself.
As you run this procedure exim will tell you what cheks are beeing performed.
It tells you which fail which succeed and why relaying works or
doesn't.
relay_domains lets you specify who can relay by fqdn.
sender_accept_relay tells you by networks a nd ip addresses.
the spec.txt has a rather nice section that sets it all out rather nicely;
and it got easier to understand since exim v3.0. I recall 1.61 relay
controls;
sender_accept_relay sender_reject_relay and sender_reject_relay_except or some silliness.
If you have further problems or need clarifications le tme know.

Regards, Kerry.
